Next syscons update (given up on numbering :) Removed screensavers from syscons, they are now LKM's. This makes it possible to do some really "interesting" screensavers... Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

Reject unreasonable values passed to CONS_HISTORY ioctl. It did not check the value and caused kernel panic when a large value was given. - Move the configuration option SC_HISTORY_SIZE from syscons.h to syscons.c. - Define the maximum total number of history lines of all consoles. It is SC_HISTORY_SIZE*MAXCONS or 1000*MAXCONS; whichever is larger. CONS_HISTORY will allow the user to set the history size up to SC_HISTORY_SIZE unconditionally (or the current height of the console if it is larger than SC_HISTORY_SIZE). If the user requests a larger buffer, it will be granted only if the total number of all allocated history lines and the requested number of lines won't exceed the maximum. - Don't free the previous history buffer and leave the history buffer pointer holding a invalid pointer. Set the pointer to NULL first, then free the buffer. PR: bin/4592

Change all #includes to follow the current Berkeley style. Some of these ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference. This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following: rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make

If you define this, it means your keyboard is actually probable using the brain-dammaged probe routine in syscons, and if the keyboard is NOT found, then you don't want syscons to activate itself further. This makes life sane for those of us who use serial consoles most of the time and want "the right thing" to happen when we plug a keyboard in.

Pass 3 of the great devsw changes most devsw referenced functions are now static, as they are in the same file as their devsw structure. I've also added DEVFS support for nearly every device in the system, however many of the devices have 'incorrect' names under DEVFS because I couldn't quickly work out the correct naming conventions. (but devfs won't be coming on line for a month or so anyhow so that doesn't matter) If you "OWN" a device which would normally have an entry in /dev then search for the devfs_add_devsw() entries and munge to make them right.. check out similar devices to see what I might have done in them in you can't see what's going on.. for a laugh compare conf.c conf.h defore and after... :) I have not doen DEVFS entries for any DISKSLICE devices yet as that will be a much more complicated job.. (pass 5 :) pass 4 will be to make the devsw tables of type (cdevsw * ) rather than (cdevsw) seems to work here.. complaints to the usual places.. :)

Fix initialization of video_mode_ptr. It only worked if the segments in the far pointers are multiples of 4K (as is normal when the video BIOS is at seg 0xc000). Disallow mode switching if the pointer is bad. Use a new pa_to_va() macro for all BIOS and video addresses in syscons.

Make pcvt and syscons live in the same kernel. If both are enabled, then the first one in the config has priority. They can be switched using userconfig(). i386/i386/conf.c: Initialize the shared syscons/pcvt cdevsw entry to `nx'. Add cdevsw registration functions.

First round in syscons update. Several new features has been added: No kernel config options anymore besides keyboard language layout. Virtual consoles are now dynamically allocated, no NCONS anymore. Software cursor blinking/nonblinking. Visual bell for laptops (don't beep at meetings :-). Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

Miscellaneous changes from Bill Paul: - /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ ethernet cards. The EtherEZ looks just like the Elite Ultra, except it has only 8K of shared memory. The only way to have it properly detected is to zero and test a few bytes of memory just about the first 8K region. If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ. I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h). - /sys/i386/isa/syscons.c wraps at the next to the last column rather than the last column, like it should. You don't really notice this unless you use certain programs that write all the way out to, say, the 80th column, like VMSmail. Along with a one-line fix for this are some changes to implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your config file and give it a try. :) Submitted by: wpaul

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

Pass 3 of the great devsw changes most devsw referenced functions are now static, as they are in the same file as their devsw structure. I've also added DEVFS support for nearly every device in the system, however many of the devices have 'incorrect' names under DEVFS because I couldn't quickly work out the correct naming conventions. (but devfs won't be coming on line for a month or so anyhow so that doesn't matter) If you "OWN" a device which would normally have an entry in /dev then search for the devfs_add_devsw() entries and munge to make them right.. check out similar devices to see what I might have done in them in you can't see what's going on.. for a laugh compare conf.c conf.h defore and after... :) I have not doen DEVFS entries for any DISKSLICE devices yet as that will be a much more complicated job.. (pass 5 :) pass 4 will be to make the devsw tables of type (cdevsw * ) rather than (cdevsw) seems to work here.. complaints to the usual places.. :)

Fix UserConfig w/syscons. The 'getchar' function in syscons (sccngetc) is used by UserConfig to get keyboard input from the user. When it was modified to use the shared keyboard port routines it used the port passed in during the probe routine. Since the probe routine was not yet called, the port was set to 0, which is obviously not going to work. Pre-initialize sc_port to IO_KBD which is really a kludge, but it's how the previous driver did it's job. Found by: remote GDB

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it. It was broken by setting the initial scr_buf to `buffer' instead of Crtat. `buffer' was full of nulls and the first scroll cleared everything above the things written through syscons.

The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

Hack workaround XFree86 switching failure when used with /dev/sysmouse and xdm, possibly in general. What was happening was that the server was doing a tcsetattr(.. TCSADRAIN) on the mouse fd after a write. Since /dev/sysmouse had a null t_oproc, the drain failed with EIO. Somehow this spammed XFree86 (!@&^#%*& binary release!!), and the driver was left in a bogus state (ie: switch_in_progress permanently TRUE). The simplest way out was to implement a dummy scmousestart() routine to accept any characters from the tty system and toss them into the void. It would probably be more correct to intercept scwrite()'s to the mouse device, but that's executed for every single write to the screen. Supplying a start routine to eat the characters is only executed for the mouse port during startup/shutdown, so it should be faster.

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it. It was broken by setting the initial scr_buf to `buffer' instead of Crtat. `buffer' was full of nulls and the first scroll cleared everything above the things written through syscons.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

Fixes annoying behavior and a bug regarding the destructive cursor (CHAR_CURSOR) 1. Reduced the number of calls to set_destructive_cursor(). The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe.

Alot of fixes from kazu: 1. All the suggestions earlier made by Bruce: renaming some symbols, stricter error checking, removing redundant code, etc. 2. The `psm' driver preserves the default counter resolution and report rate, whatever they are after reset. (Based on reports and suggestion from Nate and Rob Bolin). 3. The `psm' driver now does not check the so-called sync. bit in the first byte of the data packet by default, so that the tapping feature of ALPUS GlidePoint works (based on reports from Louis Mamakos). I tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found no problem; tapping worked. It appears ALPUS produces several models of GlidePoint. I hope the other models are OK too. The check code can still be activated by defining the PSM_CHECKSYNC option in the config file. (The bit checking slightly reduces, if not completely eliminates, weird mouse behavior cased by unsynchronized mouse data packets. It also helps us to detect if the mouse interrupt can ever be lost. But, well, if there are devices which cannot be supported this way...) 4. The `psm' driver does not include the protocol emulation code by default. The code can still be compiled in if the PSM_EMULATION option is specified in the config file. Louis Mamakos suggests the emulation code is putting too much in the kernel, and `moused' works well. I will think about this later and decide if the entire emulation code should be removed. 5. And, of course, the fix in `scprobe()' from Bruce to cure the UserConfig problem. My code in `kbdio.c' is slightly different from his patch, but has the same effect. There still is a possibility that `scprobe()' gets confused, if, for whatever reasons, the user holds down a key for very long time during the boot process. But we cannot cope with everything, can we? Submitted by: Kazutaka YOKOTA (yokota@zodiac.mech.utsunomiya-u.ac.jp)

Alot of fixes from kazu: 1. All the suggestions earlier made by Bruce: renaming some symbols, stricter error checking, removing redundant code, etc. 2. The `psm' driver preserves the default counter resolution and report rate, whatever they are after reset. (Based on reports and suggestion from Nate and Rob Bolin). 3. The `psm' driver now does not check the so-called sync. bit in the first byte of the data packet by default, so that the tapping feature of ALPUS GlidePoint works (based on reports from Louis Mamakos). I tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found no problem; tapping worked. It appears ALPUS produces several models of GlidePoint. I hope the other models are OK too. The check code can still be activated by defining the PSM_CHECKSYNC option in the config file. (The bit checking slightly reduces, if not completely eliminates, weird mouse behavior cased by unsynchronized mouse data packets. It also helps us to detect if the mouse interrupt can ever be lost. But, well, if there are devices which cannot be supported this way...) 4. The `psm' driver does not include the protocol emulation code by default. The code can still be compiled in if the PSM_EMULATION option is specified in the config file. Louis Mamakos suggests the emulation code is putting too much in the kernel, and `moused' works well. I will think about this later and decide if the entire emulation code should be removed. 5. And, of course, the fix in `scprobe()' from Bruce to cure the UserConfig problem. My code in `kbdio.c' is slightly different from his patch, but has the same effect. There still is a possibility that `scprobe()' gets confused, if, for whatever reasons, the user holds down a key for very long time during the boot process.

A fix/work-around for ThinkPad 535. Add a new configuration flag, KBD_NORESET (0x20) to tell scprobe() not to reset the keyboard. IBM ThinkPad 535 has the `Fn' key with which the user can perform certain functions in conjunction with other keys. For example, `Fn' + PageUP/PageDOWN adjust speaker volume, `Fn' + Home/End change brightness of LCD screen. It can also be used to suspend the system. It appears that these functions are implemented at the keyboard level or the keyboard controller level and totally independent from BIOS or OS. But, if the keyboard is reset (as is done in scprobe()), they become unavailable. (There are other laptops which have similar functions associated with the `Fn' key. But, they aren't affected by keyboard reset.) ThinkPad 535 doesn't have switches or buttons to adjust brightness and volume, or to put the system into the suspend mode. Therefore, it is essential to preserve these `Fn' key functions in FreeBSD. The new flag make scprobe() skip keyboard reset. If this flag is not set, scprobe() behaves in the same say as before. (If we only knew a way to detect ThinkPad 535, we could skip keyboard reset automatically, but...)

Preserve some bits in the keyboard controller command byte when resetting the keyboard. Well, sorry, this bug is totally my fault. I DID intend to preserve them, but somehow I failed. The bug puts some old keyboard controllers in a strange state, resulting in keyboard freeze or random key input. The fix closes PR kern/3067.

Alot of fixes from kazu: 1. All the suggestions earlier made by Bruce: renaming some symbols, stricter error checking, removing redundant code, etc. 2. The `psm' driver preserves the default counter resolution and report rate, whatever they are after reset. (Based on reports and suggestion from Nate and Rob Bolin). 3. The `psm' driver now does not check the so-called sync. bit in the first byte of the data packet by default, so that the tapping feature of ALPUS GlidePoint works (based on reports from Louis Mamakos). I tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found no problem; tapping worked. It appears ALPUS produces several models of GlidePoint. I hope the other models are OK too. The check code can still be activated by defining the PSM_CHECKSYNC option in the config file. (The bit checking slightly reduces, if not completely eliminates, weird mouse behavior cased by unsynchronized mouse data packets. It also helps us to detect if the mouse interrupt can ever be lost. But, well, if there are devices which cannot be supported this way...) 4. The `psm' driver does not include the protocol emulation code by default. The code can still be compiled in if the PSM_EMULATION option is specified in the config file. Louis Mamakos suggests the emulation code is putting too much in the kernel, and `moused' works well. I will think about this later and decide if the entire emulation code should be removed. 5. And, of course, the fix in `scprobe()' from Bruce to cure the UserConfig problem. My code in `kbdio.c' is slightly different from his patch, but has the same effect. There still is a possibility that `scprobe()' gets confused, if, for whatever reasons, the user holds down a key for very long time during the boot process. But we cannot cope with everything, can we? Submitted by: Kazutaka YOKOTA (yokota@zodiac.mech.utsunomiya-u.ac.jp)

/* CONTROLLER ERROR
* This is serious; we are left with the disabled keyboard intr.
*/
The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

Fixes annoying behavior and a bug regarding the destructive cursor (CHAR_CURSOR) 1. Reduced the number of calls to set_destructive_cursor(). The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it.

/* initialize cursor stuff */
Fixes annoying behavior and a bug regarding the destructive cursor (CHAR_CURSOR) 1. Reduced the number of calls to set_destructive_cursor(). The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

Hack workaround XFree86 switching failure when used with /dev/sysmouse and xdm, possibly in general. What was happening was that the server was doing a tcsetattr(.. TCSADRAIN) on the mouse fd after a write. Since /dev/sysmouse had a null t_oproc, the drain failed with EIO. Somehow this spammed XFree86 (!@&^#%*& binary release!!), and the driver was left in a bogus state (ie: switch_in_progress permanently TRUE). The simplest way out was to implement a dummy scmousestart() routine to accept any characters from the tty system and toss them into the void. It would probably be more correct to intercept scwrite()'s to the mouse device, but that's executed for every single write to the screen. Supplying a start routine to eat the characters is only executed for the mouse port during startup/shutdown, so it should be faster.

Obtained from: partly from ancient patches of mine via 1.1.5 Introduce TS_CONNECTED and TS_ZOMBIE states. TS_CONNECTED is set while a connection is established. It is set while (TS_CARR_ON or CLOCAL is set) and TS_ZOMBIE is clear. TS_ZOMBIE is set for on to off transitions of TS_CARR_ON that occur when CLOCAL is clear and is cleared for off to on transitions of CLOCAL. I/o can only occur while TS_CONNECTED is set. TS_ZOMBIE prevents further i/o. Split the input-event sleep address TSA_CARR_ON(tp) into TSA_CARR_ON(tp) and TSA_HUP_OR_INPUT(tp). The former address is now used only for off to on carrier transitions and equivalent CLOCAL transitions. The latter is used for all input events, all carrier transitions and certain CLOCAL transitions. There are some harmless extra wakeups for rare connection- related events. Previously there were too many extra wakeups for non-rare input events. Drivers now call l_modem() instead of setting TS_CARR_ON directly to handle even the initial off to on transition of carrier. They should always have done this. l_modem() now handles TS_CONNECTED and TS_ZOMBIE as well as TS_CARR_ON. gnu/isdn/iitty.c: Set TS_CONNECTED for first open ourself to go with bogusly setting CLOCAL. i386/isa/syscons.c, i386/isa/pcvt/pcvt_drv.c: We fake carrier, so don't also fake CLOCAL. kern/tty.c: Testing TS_CONNECTED instead of TS_CARR_ON fixes TIOCCONS forgetting to test CLOCAL. TS_ISOPEN was tested instead, but that broke when we disabled the clearing of TS_ISOPEN for certain transitions of CLOCAL. Testing TS_CONNECTED fixes ttyselect() returning false success for output to devices in state !TS_CARR_ON && !CLOCAL. Optimize the other selwakeup() call (this is not related to the other changes). kern/tty_pty.c: ptcopen() can be declared in traditional C now that dev_t isn't short.

/* make screensaver happy */
Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Changed mouse functionality a bit, now the pointer disappears if there is keyboard input. The mousepointer is shown again immediately if moved.

case CONS_CURRENT: /* get current adapter type */
The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

case CONS_BLANKTIME: /* set screen saver timeout (0 = no saver) */
1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this. Reviewed by: sos

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Fixes annoying behavior and a bug regarding the destructive cursor (CHAR_CURSOR) 1. Reduced the number of calls to set_destructive_cursor(). The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

First round in syscons update. Several new features has been added: No kernel config options anymore besides keyboard language layout. Virtual consoles are now dynamically allocated, no NCONS anymore. Software cursor blinking/nonblinking. Visual bell for laptops (don't beep at meetings :-). Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

/* make screensaver happy */
Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded.

1. Avoid a race in scclose(). tty.c has kludges so that the race is actually harmless. 2. Fixed code to match comment in scintr(). 3. Don't allow even root to take control of the machine when securelevel > 0. I've secured the accesses to PSL_IOPL in all drivers and asked pst to review it, but he seems to be busy. Write access to /dev/kmem and other critival devices currently leaks across raisings of securelevel via open fd's, so there may as well be a similar leak for PSL_IOPL. 4. (Most important.) Don't corrupt memory beyond the screen buffers if the cursor happens to be off the 80x25 screen when syscons starts. 5. Fix console cursor update (not perfect yet). Submitted by: bruce ~

Add a new keyboard mode K_CODE. Returns a single byte for each key much like the scancode mode. However the keys that (for no good reason) returns extension codes etc, are translated into singlebyte codes. Needed by libvgl. This makes life ALOT easier, also the XFree86 folks could use this.

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it. It was broken by setting the initial scr_buf to `buffer' instead of Crtat. `buffer' was full of nulls and the first scroll cleared everything above the things written through syscons.

Fixes annoying behavior and a bug regarding the destructive cursor (CHAR_CURSOR) 1. Reduced the number of calls to set_destructive_cursor(). The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

Move the inline code for waking up writers to a new function ttwwakeup(). The conditions for doing the wakeup will soon become more complicated and I don't want them duplicated in all drivers. It's probably not worth making ttwwakeup() a macro or an inline function. The cost of the function call is relatively small when there is a process to wake up. There is usually a process to wake up for large writes and the system call overhead dwarfs the function call overhead for small writes.

Hack workaround XFree86 switching failure when used with /dev/sysmouse and xdm, possibly in general. What was happening was that the server was doing a tcsetattr(.. TCSADRAIN) on the mouse fd after a write. Since /dev/sysmouse had a null t_oproc, the drain failed with EIO. Somehow this spammed XFree86 (!@&^#%*& binary release!!), and the driver was left in a bogus state (ie: switch_in_progress permanently TRUE). The simplest way out was to implement a dummy scmousestart() routine to accept any characters from the tty system and toss them into the void. It would probably be more correct to intercept scwrite()'s to the mouse device, but that's executed for every single write to the screen. Supplying a start routine to eat the characters is only executed for the mouse port during startup/shutdown, so it should be faster.

The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

Make syscons replicate a mousesystems mouse on minor 128.. This enables other consumers of the mouse, to get it info via moused/syscons. In order to use it run moused (from sysconfig), and then tell your Xserver that it should use /dev/sysmouse (mknod sysmouse c 12 128) and it a mousesystems mouse. Everybody will be happy then :) Remember that moused still needs to know what kind of mouse you have.. Comments welcome, as is test results...

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here.

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it. It was broken by setting the initial scr_buf to `buffer' instead of Crtat. `buffer' was full of nulls and the first scroll cleared everything above the things written through syscons.

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

First round in syscons update. Several new features has been added: No kernel config options anymore besides keyboard language layout. Virtual consoles are now dynamically allocated, no NCONS anymore. Software cursor blinking/nonblinking. Visual bell for laptops (don't beep at meetings :-). Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

Fixes annoying behavior and a bug regarding the destructive cursor (CHAR_CURSOR) 1. Reduced the number of calls to set_destructive_cursor(). The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this. Reviewed by: sos

/* make screensaver happy */
Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Don't allow even root to take control of the machine when securelevel > 0. I've secured the accesses to PSL_IOPL in all drivers and asked pst to review it, but he seems to be busy. Write access to /dev/kmem and other critival devices currently leaks across raisings of securelevel via open fd's, so there may as well be a similar leak for PSL_IOPL. 4. (Most important.)

The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

Bruce pointed out a bogon: cur_console is NULL when copy_font() is first called from scinit(). This is apparently harmless when scinit() is called early from sccninit() - page 0 is apparently mapped r/w then, and 0->status contains suitable garbage. However, when there is a serial console, scinit() is first called from scattach() when the page tables are completely initialized, so the NULL pointer causes a panic. Submitted by: bruce

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it. It was broken by setting the initial scr_buf to `buffer' instead of Crtat. `buffer' was full of nulls and the first scroll cleared everything above the things written through syscons.

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

Virtual consoles are now dynamically allocated, no NCONS anymore. Software cursor blinking/nonblinking. Visual bell for laptops (don't beep at meetings :-). Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

Fixes annoying behavior and a bug regarding the destructive cursor (CHAR_CURSOR) 1. Reduced the number of calls to set_destructive_cursor(). The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

Bruce pointed out a bogon: cur_console is NULL when copy_font() is first called from scinit(). This is apparently harmless when scinit() is called early from sccninit() - page 0 is apparently mapped r/w then, and 0->status contains suitable garbage. However, when there is a serial console, scinit() is first called from scattach() when the page tables are completely initialized, so the NULL pointer causes a panic. Submitted by: bruce

1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this. Reviewed by: sos

Some news for syscons (long overdue): Real support for a Textmode mousecursor, works by reprogramming the charset. Together with this support for cut&paste in text mode. To use it a userland daemon is needed (moused), which provides the interface to the various mice protokols. Bug fixes here and there, all known PR's closed by this update.

Third round in syscons update. Display update method changed, now allways write in memory buffer, then periodically update physical display. Speed improvements (now > 5 times faster than the old syscons). History now circular buffer, with changeable size. History scroll by up/down line, up/down page, home and end. Backtab proberly implemented. Now space for 96 function keys, 63 allocated standard, default now SCO/SYSV compat again as in the old days. New keyboard definition files ~share/syscons/keymaps/* Misc fixes for old "hacks" that broke SCO/SYSV compat. More that I forgot before writing this...

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it. It was broken by setting the initial scr_buf to `buffer' instead of Crtat. `buffer' was full of nulls and the first scroll cleared everything above the things written through syscons.

First round in syscons update. Several new features has been added: No kernel config options anymore besides keyboard language layout. Virtual consoles are now dynamically allocated, no NCONS anymore. Software cursor blinking/nonblinking. Visual bell for laptops (don't beep at meetings :-). Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

scgetc() referred to `spcl' in different ways when a key is pressed and released. It should use `spcl' consistently in both cases, otherwise shift/control/alt state may not be correctly set/reset. (Even with this fix, you can still make syscons confused and fail to change internal state if you really want to, by installing a really arcane and artificial keymap.) PR: i386/4030 Reviewed by: sos

Interim patch/kludge for keyboard lock-up when `kbdcontrol' tries to change typematic rate, or the X server (XFree86 or Accelerated X) starts up. So far, there have been two independent reports from Dell Latitude XPi notebook/laptop owners. The Latitude seems to be the only system which suffers from this problem. (I don't know the problem is with the entire Latitude line or with only some Latitude models) No problem report has been heard about other systems (I certainly cannot reproduce the problem in my -current and 2.2 systems). In 3.0-CURRENT, 2.2-RELEASE and 2.2-GAMMA-970310, when programming the keyboard LED/repeat-rate, `set_keyboard()' in `syscons' tells the keyboard controller not to generate keyboard interrupt (IRQ1) and then enable tty interrupts, expecting the keyboard interrupt doesn't occur. It appears that somehow Latitude's keyboard controller still generates the keyboard interrupt thereafter, and `set_keyboard()' doesn't see the return code from the keyboard because it is consumed by the keyboard interrupt handler. The patch entirely disables tty interrupts while setting LED and typematic rate in `set_keyboard()', making the routine behave more like the previous versions of `syscons' (versions in 2.1.X and 2.2-ALPHA, -BETA, and some -GAMMAs). The reporter said this patch eliminated the problem. (I also found another typo/bug, but the reporter and I found that it wasn't the cause of the problem...) This should go into RELENG_2_2.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Added support for many more videomodes, including graphic modes up til 320x200 256col VGA. This is nessesary for the iBCS stuff to work right. (And we get the benefit of more video modes). Uses the videocard BIOS to optain mode tables. Added a "green" saver, switches off the syncs for "green" monitors. Reviewed by: Submitted by: Obtained from:

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this. Reviewed by: sos

1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this. Reviewed by: sos

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this. Reviewed by: sos

set_font_mode();
Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

First round in syscons update. Several new features has been added: No kernel config options anymore besides keyboard language layout. Virtual consoles are now dynamically allocated, no NCONS anymore. Software cursor blinking/nonblinking. Visual bell for laptops (don't beep at meetings :-). Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this. Reviewed by: sos

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)
